# The makefile built from this file lives in the language subdirectory.
# Its purpose is to provide support for:
#
# 1) recursion where necessary, and only then (building .o's), and
# 2) building and debugging cc1 from the language subdirectory, and
# 3) nothing else.
#
# The parent makefile handles all other chores, with help from the
# language makefile fragment, of course.
#
# The targets for external use are:
# all, TAGS, ???mostlyclean, ???clean.

# This makefile will only work with Gnu make.
# The rules are written assuming a minimum subset of tools are available:
#
# Required:
#      MAKE:    Only Gnu make will work.
#      MV:      Must accept (at least) one, maybe wildcard, source argument,
#               a file or directory destination, and support creation/
#               modification date preservation.  Gnu mv -f works.
#      RM:      Must accept an arbitrary number of space separated file
#               arguments, or one wildcard argument. Gnu rm works.
#      RMDIR:   Must delete a directory and all its contents. Gnu rm -rf works.
#      ECHO:    Must support command line redirection. Any Unix-like
#               shell will typically provide this, otherwise a custom version
#               is trivial to write.
#      AR:      Gnu ar works.
#      MKDIR:   Gnu mkdir works.
#      CHMOD:   Gnu chmod works.
#      true:    Does nothing and returns a normal successful return code.
#      pwd:     Prints the current directory on stdout.
#      cd:      Change directory.
#
# Optional:
#      BISON:   Gnu bison works.
#      FLEX:    Gnu flex works.
#      Other miscellaneous tools for obscure targets.

# Suppress smart makes who think they know how to automake Yacc files
